Security concerns

Contrary to simple models (and perhaps common belief), the contents of modern SDRAM modules are not lost immediately when the computer is shut down; instead, the contents fade away, a process that takes only seconds at room temperatures, but which can be extended to minutes at low temperatures. It is therefore possible to recover any data stored in ordinary working memory (i.e. the SDRAM modules).[7] This is sometimes referred to as a cold boot attack or ice-man attack.
